Katerina Tsili

Summary
Detail-oriented professional with experience working in regulated environments, where I’ve handled complex information, reviewed documentation, and produced clear, structured written work. I’m used to managing multiple priorities under pressure while maintaining accuracy and meeting deadlines, and I take a practical, organised approach to problem-solving. I have a strong interest in financial crime sparked by my Criminology degree and client onboarding, which I’ve been developing through self-directed learning in AML, KYC, and due diligence. I’m comfortable working with sensitive information, applying judgement, and communicating clearly with different stakeholders. I’m fluent in English, Greek, and Albanian, and confident working in fast-paced, client-focused environments.
